Fixed In Version:
Doc Type: Enhancement
Doc Text:
Previously, it was problematic to flip the host into the maintenance state while it was flipping between connecting and activating state. In this release, the host, regardless of its initial state before restart, will be put into maintenance mode after restarting the host using power management configuration.

Description Roman Hodain 2018-05-03 10:50:48 UTC
Description of problem:
It is not possible to flip a host to the maintenance mode in case it is connecting or activating. It is understood that some status simply cannot be interrupted a host cannot be flipped to the maintenance mode immediately, but it should be possible to flip the host to the maintenance in the nearest possible state.
It is problematic to flip the host to the maintenance state if it is flipping between connecting and activating state. It may get to the non-operation state for short period of time, but one has to monitor the host and click the button as soon as itis in the non-operational state otherwise the host can flip to connecting again.

Comment 1 Martin Perina 2018-05-16 11:19:13 UTC
I think the safest method to achieve this is to add option to switch to Maintenance mode when admin execute power management restart on a host. This way we can be sure, that host resources were cleared (we can't be sure about it for SSH restart).

Comment 3 Petr Matyáš 2020-01-24 11:25:20 UTC
The host can't be switched to Maintenance from Unassigned state, either change the summary or create a fix so it is really all situations.

Tested on ovirt-engine-4.4.0-0.14.master.el7.noarch

Comment 4 Martin Perina 2020-01-24 12:43:15 UTC
Unassigned status is hidden status and it should always be a temporary short term status. This means that engine itself should move a host from Unassgined status to some other valid status automatically. If the host stays in Unassigned status for longer time (let's say a minute or more), then please file a bug, because there is no way how administrators could handle host in Unassigned status.
